The exclusion option is not valid in this case, I just tested a couple of things with it and it still says that the files are corrupted. It's a glitch in the Kaspersky program, but not a straight forward one. If one uses support from Kaspersky they point to GOTD and vice versa ;-)

The image you uploaded two post higher, the bottom line says "Properties", that's the place to go for the unblock option. But as I said, it's better to restart the pc in safe modus and install the program there.

Down in the popup window, you'll see "Properties", there you can read the message about the blocking of the file and a button to click on to unblock it.
Oh, and it's a typo: it's gcd indeed!
The unblocking doesn't always help. The sure thing to do is re-starting the pc in safe modus and install the program as administrator from there. That works all the time!!

Neither Security Essentials in my VM nor Bitdefender in win7 can find a problem with it.

It is possible your security software is triggering on the GOTD setup & GFD files, since they are compacted & encrypted to prevent decompiling -- decompiling would be a way of reverse engineering to get the actual setup file when the GOTD is over. Some mal-ware is also compacted/encrypted to prevent security software from recognizing it. Since the security software can't see inside of the setup files, some security software just determines everything that's compacted/encrypted is mal-ware.

Solution one might be to change your brand of security software.
Solution 2 might be to work around it -- see the other threads dealing with this & similar topics.

We did find what went wrong! Kaspersky security software blocks the .gdc file from being used. Thus the installation stops (with a wrong error message).
So each time I download a GiveAwayOfTheDay program I need to right-click on the .gdc file and lift the blockage.

You enter safe mode either by pressing a function key at startup (generally F8 but check your documentation) OR by using the system configuration utility (which is probably easier if your PC already boots).

1st, Chris is right that it's likely easier [in our opinion at least] to use msconfig. If you want to try again the other way, pay attention when your PC/laptop is starting after being turned off -- not just being put to sleep -- and you might see a very brief hint on-screen to show the boot-up details. It can be a very brief window of time when F8 works -- I often just start pressing the key somewhat rapidly during boot-up. Note that on some keyboards the function keys need to be pressed in combination with some other key to work as function keys. If you do succeed in bringing up the menu for Safe Mode, note that you want the option With Networking -- otherwise the GOTD wrapper software can't phone home to verify the date so it works.

You enter safe mode either by pressing a function key at startup (generally F8 but check your documentation) OR by using the system configuration utility (which is probably easier if your PC already boots).

To use the configuration utility you just type "msconfig" (no quotes) in a "run box" which you can open by either pressing the Windows Key and R at the same time or by typing "run" in the search box and clicking the command that it finds. Once the system configuration utility starts simply select "safe boot" at the main screen, close and reboot the PC and it will start in "safe mode".

After you've installed the software repeat the msconfig process and select "normal boot".

I've tried Firefox and Chrome, but the message stays the same.
Then I tried to start the pc in safe mode, but I don't seem to find a way to do so. I either drop into the recovery disk or into Bios (where Boot Menu was enabled, but it doesn't show up when booting or re-booting.
And yes, graylox, I have unpacked the files before trying to exe them. (I use Giveawayoftheday for many years now).
I even downloaded Winrar and installed that, and unpacked the file with that.
No way... still the same message. It should be something with GOTD, because all the rest works fine, no?

As far as I see from your screenshot you are actually able to download, but can't open the downloaded .zip or .rar file.
Please don't try to run the .exe file from within the downloaded .zip or .rar file.
Open the compressed file with right click and extract the complete content to a folder.
Then you should be able to run the .exe file.

Same problem here, but I bought a new pc (Acer Aspire TC-603) and I can't install any Giveawayoftheday program. They always say that the file is corrupted.
I can download and install programs from sourceforge and all, no problem there. It's just GOTD.

If it's not your anti-virus then either you or your auto-updating PC installed something that's preventing the installation process from running.

First, make it as easy for the installer to run as possible by disconnecting all external storage devices, close all programs including your browser, and use the "run" box instead of double-clicking in Explorer.

If that doesn't work then you've got a problem because the wrapper is like Vegas and "what happens in the wrapper stays in the wrapper". Something you added since the last GOTD program you installed has "broken" the installation process (or that program broke it). It could be a Windows Update, a driver update, a driver update that's now needed because of a newly installed program or update, or simply a program not playing nice with your system.

I think you have 3 choices:
1) Do nothing, the problem may resolve itself over time, particularly if it's related to Windows Updates. You should also check to see if any Windows Updates are now available.
2) Install non-GOTD programs that you previously uninstalled (i.e. programs that you know install and run) and try to force an error. Check Event Viewer for errors that don't generate pop-ups. You can also do the same with trialware and freeware. If you can force an error then you know what to fix.
3) Uninstall updates and programs back to the last successful GOTD installation (backing up your system first). Then start adding them back, testing the latest GOTD offering as you go. When you find the culprit, you can restore from your backup and uninstall the problem. I'd start with the Windows Updates.

I have already tried twice to download software. I download click on the. Exe it extracts and then nothing! What's wrong. Previously, I never had any problems.

The first thing to check is if your security software is preventing installation. Check the anti-virus program's log. All GOTD offers are checked for viruses so any reported virus is almost certainly a false positive.

I disagree rrodken, you and everybody else who can't install the programs should complain. I don't know how GOTD tracks their success but if it's simply downloads then having a significant number of users with failed installations isn't helpful. The big unknown, however, is just how many people have problems.

If you've given the GOTD program permission to run via your security software, your PC meets the program's minimum requirements, and your account has the required permissions then the installation is either failing because of the wrapper (it's a resource hog) or the underlying program's installation routine. Unfortunately, no error messages escape the wrapper so you just have to guess what's causing the problem.

But, there may be a workaround... try today's download from Ashampoo. Can you install it? If not, visit their website from the link on the GOTD page and see if the trial version will install. If the trial version reports errors then those errors are likely preventing the GOTD version from installing. Fix them and the GOTD version should install. If the trial version installs OK then try installing the GOTD version on top of it.

I myself have had WAY TOO many problems with trying to install almost anything from this site, they should just stick to registering your own serial that you can get in your email specifically for you and if you share it they (the software provider could just blacklist it). Instead of the way it is now, but I have a feeling I'm just wasting my time on commenting so. Is a great site, just usually useless to myself and obviously to others.
Hopefully we will see improvements later. Hard to really complain when it's all free, aside for the wasted time I've tried to install soft which is never able to install.
Anyways enough of that, hope you get yours working, as for myself I'll give up for now!:)

If you mean it's unregistered... As in the GOTD readme.txt file, visiting the special leawo.com url gave you a registration code. Using that code to register PowerPoint to Video Pro should add one file, while 2 others changed -- all were/are under All Users App or Application Data.

Assuming you copied & saved that registration code, maybe it would work to try registering the app again? You may need to run as admin etc. in Vista, win7, win8 to help make sure you have permissions to add & change files.

Leawo PPT to Video Pro says it will "Keep complete features and effects of the original PowerPoint files" and that "You can also add watermark or logo to credit your work". It does not state, imply or infer that it will remove watermarks.

Google Translation of original:
This software was available as a giveaway on April 28, 2013, I have downloaded this and came to the conclusion that a watermark was still visible after converting a PowerPoint. However it was talking about the pro version. Actually we were duped here which I did not fair. They spoke about a free pro version and when I understand would be in this version certainly see no watermark. To be honest I thought. If there are still people have had this problem, I would like to know this.
